Description
Technical field
This utility model relates to measurer technical field, particularly hole taper detection instrument.
Background technology
Traditional hole taper detection method uses the indirect method of measurement, two accurate steel balls and general measurer is i.e. utilized to measure, this method requires different taper holes, will there is the accurate steel balls of two corresponding sizes, otherwise measure and cannot be carried out, therefore measure and be restricted, but in reality is measured, can run into the taper hole that various sizes are different, tapering is different, general metrological service is all difficult to provide corresponding accurate steel balls.Existing hole taper measurer, or structure complexity low cost, or operation complexity, higher to the quality level requirement of operator, this does not complys with the production requirement of batch detection.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of simple in construction, easy to operate and measure the instrument of hole taper detection accurately.
The purpose of this utility model is achieved through the following technical solutions: hole taper detection instrument, including base plate, slide block, body, test bar and amesdial, slide and be provided with slide block in the upper side of base plate, slide block slides along the length direction of base plate, pressing plate it is fixed with on slide block, workpiece is fixed on the top of slide block by pressing plate, the top opposite side of base plate is fixed with body, body is provided with test bar near slide block side by hinge pin is hinged, the head of test bar stretches in the endoporus of workpiece, body is fixed with amesdial away from slide block side, the contact of amesdial contacts all the time with the afterbody side of test bar.
Further, described base plate is provided with baffle plate along its length, fits with baffle plate in the side of slide block.
Further, the head of described test bar to the distance of hinge pin less than the afterbody of test bar to the distance of hinge pin.
Further, described body also having the spring eye of vertical direction, spring eye is positioned at the underface of test bar, is provided with spring in spring eye, and the lower end of spring is pressed on the bottom of spring eye, and the upper end of spring is fixing with the afterbody of test bar to be connected.
This utility model has the advantage that
1, simple in construction of the present utility model, low cost of manufacture, easy to operate, relatively low to the quality level requirement of operator, it is adaptable to the batch detection of product.
2, using lever principle, be hinged on body by test bar, the head of test bar stretches into inner hole of workpiece, and contact with inner hole wall all the time, measured the displacement in the tail height direction of test bar by amesdial, can indirectly draw the short transverse displacement of test bar head, and it is high to measure precision.
3, the head of test bar to the distance of hinge pin less than the afterbody of test bar to the distance of hinge pin, the number of degrees of amesdial are the data through lever amplification, can further improve certainty of measurement, reduction measurement error.
4, the lower section at test bar arranges spring, spring all the time by the head pre-pressing of test bar in workpiece inner wall, prevent test bar from producing and beat during detection, improve certainty of measurement further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-base plate, 2-baffle plate, 3-slide block, 4-pressing plate, 5-workpiece, 6-main body, 7-test bar, 8-hinge pin, 9-amesdial, 10-spring eye, 11-spring.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, hole taper detection instrument, including base plate 1, slide block 3, body 6, test bar 7 and amesdial 9, slide and be provided with slide block 3 in the upper side of base plate 1, slide block 3 slides along the length direction of base plate 1, pressing plate 4 it is fixed with on slide block 3, workpiece 5 is fixed on the top of slide block 3 by pressing plate 4, the top opposite side of base plate 1 is fixed with body 6, body 6 is provided with test bar 7 near slide block 3 side by hinge pin 8 is hinged, the head of test bar 7 stretches in the endoporus of workpiece 5, body 6 is fixed with amesdial 9 away from slide block 3 side, the contact of amesdial 9 contacts all the time with the afterbody side of test bar 7.
Further, described base plate 1 is provided with baffle plate 2 along its length, fits with baffle plate 2 in the side of slide block 3; the glide direction guaranteeing slide block 3 is straight line; and along the length direction of base plate 1, with baffle plate 2 as reference time slide block 3 slides, it is simple to slide block 3 slides along the length direction of base plate 1.
Further, the head of described test bar 7 to the distance of hinge pin 8 less than the afterbody of test bar 7 to the distance of hinge pin 8, utilizing lever principle, the upper and lower displacement of test bar 7 head is through being amplified to the upper and lower displacement of test bar 7 afterbody, and amesdial 9 can reduce error when measuring.
Further, the spring eye 10 of vertical direction is also had on described body 6, spring eye 10 is positioned at the underface of test bar 7, spring 11 is installed in spring eye 10, the lower end of spring 11 is pressed on the bottom of spring eye 10, the upper end of spring 11 is fixing with the afterbody of test bar 7 to be connected, the spring 11 top pressure effect to test bar 7 afterbody so that the head of test bar 7 is fitted in the endoporus bottom of workpiece 5 all the time.
Work process of the present utility model is as follows: workpiece 5 is fixed on the top of slide block 3 by pressing plate 4, the head of test bar 7 is stretched into the endoporus of workpiece 5, spring 11 is by the afterbody jack-up of test bar 7, the head of test bar 7 is pressed on the endoporus of workpiece 5, amesdial 9 is fixed on body 6, and the afterbody of contact with test bar 7 is contacted all the time, read the registration of amesdial 9, slide block 3 is carried over baffle plate 2 slide, workpiece 5 is moved towards the afterbody of test bar 7, now the head of test bar 7 produces relative displacement on workpiece 5 endoporus, again read off the registration of amesdial 9, the displacement of the short transverse of the head of test bar 7 can be drawn through geometrical calculation, the distance moved further according to slide block 3, hole taper can be calculated.
